The Gx5290 can change the way it is operating to either be a high speed digital I/O or to real tome compare mode. The settings will change all the Gx529x boards in the domain to operate in the same mode. The operating mode is saved to the INI file and is reapplied each time the DIO is initialized until it is changed.
In real time compare mode the output memory contains the expected vector values while the input memory contains the vector masked values. See the “Gx5290UG.pdf” for more details on the real tome compare mode operation.
The following example returns the DIO domain operating mode:
SHORT nStatus, nMode;
DioDomainGetOperatingMode (nMasterHandle, &nMode, &nStatus);
